JBL Subwoofer


  • Hello @Support Dasaita and forum members, I have recently installed an Android G13 head unit with the correct harness per the instructions.  However, my JBL Subwoofer in my 2019 4Runner is not producing any sound.  All of my other speakers are working just fine, it is just the JBL Subwoofer.  Please let me know how to enable the JBL Subwoofer in one of the Settings menus or in the Developer Menu.  Thank you! 



  • @Joseph Rohan We are wondering if you have already go to the EQ settings > volume to crank up the Sub volume.
